General
The Aquavar ABII is a self-diagnosing controller. If a problem occurs, observe the Status Code Indicator Light on the
front of the unit. No Status Code Indicator Light means either no or low input voltage (less than 50 V).
DANGER
Status Code Indicator Light is not a voltage indicator! Always turn off disconnect switch and circuit
Hazardous
breaker and wait 5 minutes before servicing. High voltage may still remain on controller.

Refer to the status code label on the side of the controller access cover to diagnose system errors. See Diagram 6 for details.

GREEN LIGHT CODES
Description
Constant Green Light indicates the pump is off. The system is in
Standby mode when there is no flow in the system and the pressure
setting has been reached. The system is in a Low Voltage condition
when the line input voltage drops below 196VAC for 1AB2 and 2AB2
controllers and 98VAC for 1151AB2 controllers.
Flashing Green Light indicates the pump is running. If pump is not
running, turn off power to controller and wait 5 minutes. Check
output power connections from controller to motor.
RED LIGHT CODES
Replace Aquavar ABII Controller
This fault is indicated if the system pressure drops 5 PSI or more
below the set pressure and the output current is less than 75% of the
motor overload setting for 10 seconds. The system will automatically
restart in 5 minutes. If 3 faults occur in an hour, the system will not
restart and will need to be manually reset. If the problem reoccurs,
please verify supply capacity, pump capacity, proper setting of the
motor overload switches and that there are no restrictions between
the supply and the pump.
This warning is indicated if there is a drastic drop in system pressure
in a short amount of time. The warning will not impact operation.
The pump will continue to run. This warning can be caused by low air
pressure in the tank or the tank bladder may have failed. This can also
be caused by extreme changes in flow. The error is cleared each time
the pump starts. If the error reoccurs often, check the air pressure in
the tank. Before checking tank air pressure, turn power to control off
to prevent pump from turning on. Relieve system pressure by opening
a faucet.
This fault indicates a problem with the pressure sensor feedback.
Verify the connections from the Aquavar ABII Controller to the
pressure sensor. Turn power to controller off and wait 5 minutes.
Remove controller access panel. Be sure sensor cable is wired as
shown in Diagram 4. If cable is wired correctly, check the voltage on
the Input (White) pressure sensor terminal connection in the
Aquavar ABII controller. Using a DC voltmeter, connect the positive
lead to the Input (White) pressure sensor terminal connection, connect
the negative lead to the Com. (Black) pressure sensor terminal
connection. Turn power to controller on. The DC voltage measured
should be in the valid range of 0.5 Vdc to 4.5 Vdc (+/- 0.2 Vdc). If the
voltage is outside this range, replace pressure sensor.
This fault can be caused by mechanical binding from debris in pump
or from an electrical failure in the motor. Verify the error by turning
power to controller off for 1 minute and then on. Pump must be
checked if error persists.
